[ARM] 3744/1: MMC: mmcqd gets stuck when block queue is plugged
Patch from Juha [êölä
When the block queue is plugged, mq->req must be set to NULL.
Otherwise mq->req might be left non-NULL, even though mmcqd is
not processing a request, thus preventing the MMC queue thread from
being woken up when new requests do arrive.
